The Ojo Lagoon, located in the heart of San Vicente, Buenos Aires province, is consolidating as an emblematic natural space thanks to a series of community actions and improvement works led by Mayor Nicolás Mantegazza.
Within the framework of the Tourism and Environmental Development Plan, neighbors, local institutions, park rangers, and the Kayakers Club participated in a working day that reaffirms the municipal commitment to the preservation and beautification of this urban reserve.
“We are happy to build a more sustainable future for our Natural Reserve together,” Mantegazza expressed.
Ecological restoration and beautification of the water mirror
New works to consolidate the Lagoon as a recreational and tourist space. The tasks included:
- Cleaning of the water mirror
- Beautification of the natural surroundings
- Incorporation of a boat for sanitation and conservation
These actions allow to intensify environmental care, improve conditions for community enjoyment, and strengthen the district’s tourist profile. The Lagoon is envisioned as a meeting place, recreation spot, and ecotourism destination, with expanding infrastructure and a participatory approach.

Biodiversity and ecological value of Ojo Lagoon in San Vicente
A natural refuge of 180 hectares with over 135 bird species.
The Lagoon is part of the Samborombón River basin and hosts a rich diversity of flora and fauna:
- Native fauna: capybaras, coypus, tegus, opossums, guinea pigs, water turtles, and over 135 bird species
- Aquatic and riparian vegetation: reeds, water hyacinths, algae, water flowers, eucalyptus, and willows
This ecosystem is essential for water regulation, species conservation, and urban environmental balance.
History, culture, and outdoor recreation
A foundational space with local identity and multiple activities.
Historically known as Reducción Lagoon, due to its proximity to an ancient indigenous reduction, Ojo Lagoon is also a cultural site. The area is home to the Historical Museum October 17, which houses the remains of General Perón. Additionally, the area offers:
- Trails and rest areas
- Recreational fishing (with challenges due to aquatic vegetation)
- Biking and hiking
- Birdwatching, with circuits like the “Camino del Sapo”
Citizen participation and environmental planning
An ecological reserve growing with the contribution of the entire community.
The municipal management promotes a future-oriented approach, involving neighbors and institutions in the design of environmental policies.
Ojo Lagoon becomes a model of urban restoration, where ecotourism, environmental education, and local identity come together to build a more sustainable, safe, and accessible space.
